CDR-23 is MOST bus. That can easily be gotten around. The bigger problem is the immobiliser. The older radios were directly coded in the radio. The CDR-23 is coded in the immobiliser, so there is a good chance it won't work with an older immobiliser (pre 2003)

Get the connential unit. It looks OEM

Porsche radios aren't that great anyway
